Sony India — Worst customer service

It's been a pathetic experience that I am facing from the last 1week...The display of my TV is not working eventhough the power supply is turned on... sometimes it gets turned on for a few min and will automatically get turned off...i have contacted your customer care and service department and still I haven't received any support from them...They have wasted my 1week time waiting for them ...So I would like to register a complaint against the service centre located in Kottayam who has received my service request and not yet responded and the service person named Rahul whom the service department has assigned to do the repair...I look forward to know the status of my complaint as soon as possible..
